The NJJ231400 Circuit Breaker is an industrial-grade protective device designed for dependable power distribution in demanding environments. With a 400A rating, a 3-pole configuration, and 240V operation, it delivers reliable, synchronized fault interruption to protect equipment and personnel. This part is ideal for maintenance, retrofit, and replacement projects where exact specifications matter, and matching the right part number ensures compatibility.
Designed for three-phase power systems, the NJJ231400 provides balanced protection across all phases—crucial for preventing unbalanced faults that can damage motors, pumps, and conveyors. Its 400A rating makes it suitable for high-demand feeders and heavy-duty equipment, while the 3-pole design ensures a clean, simultaneous disconnect of all phases during a fault. This combination reduces downtime and simplifies fault isolation in complex industrial panels.
To ensure a seamless fit, verify that your panel accepts a 3-pole, 240V device and that the amperage aligns with your system’s load requirements. The NJJ231400 part number is the best reference for compatibility, helping you avoid mismatched devices that could compromise protection or performance. Have a licensed electrician perform installation, follow all safety protocols, and conduct a full system test after replacement.
